Fig. 2From: The impact of nucleic acid testing to detect human immunodeficiency virus, hepatitis C virus, and hepatitis B virus yields from a single blood center in China with 10-years reviewNon-discriminating reactive NAT yields in the blood service centers. The scale at the left indicates NAT yields (per million) in the TMA method, the donations were non-discriminating reactive (□); the scale at the right indicates the LOD (IU/mL) of different reagents in the TMA method in ID-NAT assays (○) and HBV discriminatory assay (●)Back to article page
